MK2732-05

MK2732-05 Low Phase Noise VCXO+Multiplier Description The MK2732-05 is a low cost, low jitter, high performance VCXO and PLL clock synthesizer designed to replace expensive discrete VCXOs and multipliers. The on-chip Voltage Controlled Crystal Oscillator (VCXO) accepts a 0 to 3 V input voltage to cause the output clocks to vary by ±100 ppm. Using ICS/MicroClock’s patented VCXO and analog Phase-Locked Loop (PLL) techniques, the device uses an inexpensive 10 MHz to 14.318 MHz pullable crystal input to produce one or two output clocks. ICS manufactures the largest variety of Set-Top Box and multimedia clock synthesizers for all applications. Consult ICS to eliminate VCXOs, crystals and oscillators from your board.
